3/4 inch (2 cm)
What is the main reason that it is difficult to control EAB?
The adult insects can fly very long distances
Symptoms of early infestation can be very hard to detect
No animals eat EAB because they are toxic
The insects live a long time

Which picture does NOT show ash leaves?
Which EAB life stage does the most damage to the tree?
The most likely time of year that EAB adults would be active in Oregon is:
March - April
April - May
June - July
August - September
In which of the following scenarios would you feel it is NOT appropriate to report EAB or ALB?
You collect an insect specimen that looks like ALB. You compare this specimen to the look-alikes in Oregon. It does not appear to be any of the look-alikes.
You are driving in the country and notice a stand of unhealthy Oregon ash. You do not stop but you make a mental note of where the stand is located so you can report it later.
Using your binoculars, you notice what looks like D-shaped exit holes on the upper branches of an unhealthy ash tree in the woods behind your house. You also notice epicormic shoots stemming from the lower trunk. You collect a branch from the tree and confirm that it is an ash.
You notice a large amount of frass on the branches of a horsechestnut outside of your local community center. Upon closer inspection, you find round exit holes that are slightly smaller than a dime.
Which of the following is NOT a typical sign/symptom of EAB?
Woodpecker damage (stripping away the bark of the tree)
D-shaped exit holes that are 1/8-inch in diameter
Epicormic branches (shoots coming from the trunk of the tree)
Sap oozing from the trunk
